Brazil has been facing an increasing frequency of extreme weather events, including severe droughts and floods, which scientists attribute to climate change. Forests play a critical role in mitigating these challenges by preventing erosion, reducing pollution, and helping to store water in soil and aquifers. This contributes significantly to water security in the country.
In response, organizations throughout Brazil have been leading efforts to reforest areas that have been cleared, particularly along rivers and other water sources, to help counteract the damaging effects of climate change. These efforts also aim to safeguard wildlife habitats and enhance biodiversity. Experts suggest that broader support and stronger federal policies are necessary to scale up these initiatives effectively.
In the southern Brazilian state of Paraná, the Wildlife Research and Environmental Education Society (SPVS) has been working to restore degraded lands, particularly in the town of Antonina. Over the past two decades, they have transformed vast buffalo pastures into thriving forests, covering an area of 19,000 hectares.
These restored areas provide multiple benefits, including improved water security, carbon capture, and financial incentives through Ecological ICMS, a tax policy that compensates municipalities for establishing protected areas. The work of SPVS is part of a larger project to conserve the Atlantic Forest, one of the most biodiversity-rich regions in the world.
Brazil’s water crisis is becoming more severe, with freshwater coverage declining across much of the country. Research shows that 18.3 million hectares of Brazil’s land, or 2% of the country, was covered by freshwater in 2023, marking a significant drop from historical averages.
To address this, conservation groups and government agencies have turned to natural solutions like reforestation. Experts emphasize that preserving and restoring forests is essential for drought protection, as tree roots help retain water in the ground, and tree canopies reduce evaporation, providing a buffer against extreme weather.
Riparian forests, or those found along rivers, offer additional benefits by protecting against flooding. During periods of heavy rain, they help slow the flow of water into rivers, reducing the risk of floods and preventing soil erosion.
The Taquari Valley in Rio Grande do Sul, which has been hit by multiple floods since late 2023, is a prime example of the need for riparian forest restoration. Local groups, including the Taquari Valley Riparian Forest Movement, are working to restore the region’s native vegetation to reduce flood damage and improve soil health.
Riparian forests also provide numerous other ecosystem services, such as reducing water pollution and supporting biodiversity. The preservation of these forests helps prevent pollutants like sediments, pesticides, and fertilizers from entering water bodies.
Furthermore, a diverse forest ecosystem supports a wide range of species and maintains ecological corridors, which are crucial for wildlife movement and survival. Restoration efforts must be carefully planned, taking into account various environmental factors such as soil type, local climate, and topography to maximize their effectiveness.
While local restoration projects have shown promising results, experts argue that the scale of these efforts must be expanded to have a lasting national impact. Brazil’s Forest Code, which mandates the protection of vegetation along water bodies, has faced criticism for its 2012 amendments, which reduced the required size of protective vegetation buffers.
While some officials defend the changes, claiming that states and municipalities can still impose stricter regulations, conservationists worry that these adjustments have weakened protections and hindered broader conservation efforts.
The federal government has been implementing several initiatives to support environmental conservation, such as providing financial incentives for rural landowners to meet environmental standards. Recent policies, including the National Plan for the Recovery of Native Vegetation, aim to allocate funds from water usage to support the restoration of key environmental areas.
Additionally, low-interest credit lines are being offered to landowners who commit to conserving native vegetation, highlighting the potential for integrating environmental goals into economic frameworks.
Despite these challenges, many conservationists remain hopeful about the future. Clóvis Ricardo Schrappe Borges, founder of SPVS, is optimistic that better management of natural reserves could inspire similar efforts across both public and private lands.
By recognizing the ecological and economic value of conservation, Brazil has the potential to create a more resilient environment and address the growing impacts of climate change.
